Title: Magnetic head
Inventor: MATSUOKA NARITSUYO
IPC: G11B5/58
Filed: 1985-01-14
Abstract: PURPOSE:To reduce the overall height of a magnetic head and to shorten the length of a magnetic path and improve magnetic efficiency by fitting a back core between a media sliding part and a gimbals surface. CONSTITUTION:When the magnetic head is assembled, a core 5 is joined by supports 1 and 3, the media sliding part 6 is ground, polished, and finished to specific size, and the back core 4 wound with a coil 8 is adhered and joined to the core 5 to form a closed magnetic path. At this time, the back core 4 is joined to the support 3 as well to increase the joining strength. Then, it is fitted at the prescribed position of a gimbals 7. Consequently, it is not necessary to provide the back core and coil to the back side of the gimbals 7, so the overall height of the head is reduced; and the back core 4 is provided closer to the media sliding part 6 than to the gimbals 7, so the magnetic path length is increased greatly, thereby improving the magnetic efficiency.
